Hercules, CA Building Setbacks & Zoning: Structure Height Limits (2026)

500 of the Hercules Zoning Ordinance, fixes a maximum building height for each residential zoning district. The single-family districts, RS-E and RS-L, are both capped at 35 feet. The multifamily districts step up with density: RM-L allows 45 feet, RM-M allows 60 feet, and RM-H, the highest-density multifamily district, allows 90 feet. Footnote (7) to the table carves out an exception within RM-L: even though the district-wide cap is 45 feet, "maximum height for single-family housing and duets/duplexes is 35 feet" if that housing type is built in the RM-L district, matching the lower single-family standard rather than the district's general multifamily ceiling.

800 for supplemental height provisions and Chapter 13-32 for parking, both of which a builder must also check before finalizing plans. 2 as part of every residential building permit, and any design exceeding the applicable district cap must first secure relief through a variance or an approved planned development modification.
